DocMerge Privacy Policy

DocMerge is a lightweight tool that merges Microsoft Word (.docx) files. We designed it to be private by default: uploads are processed ephemerally and temporary working files are deleted after your merged document is sent back to you.

What we process

• Files you upload (single .docx or a .zip of folders): processed only to create your merged file, then the temporary working folder is deleted automatically after the response is sent.
• Minimal request data: IP address, timestamps, request ID, counts/sizes of files (not contents), error traces if something fails. We use this for rate limiting, abuse prevention, troubleshooting, and basic reliability analytics.
• Local preferences (in your browser): heading toggle, color, size, and output filename. Stored in localStorage on your device, not on our servers.

What we do not do

• No long-term storage of your uploaded files or merged outputs.
• No model training or content mining using your files.
• No account creation required.

Ads & third parties

We use Google AdSense to help fund free usage. AdSense may set cookies or use device identifiers to measure performance or deliver (non-)personalized ads depending on your region and consent.

• Learn more about how Google uses data: policies.google.com/technologies/partner-sites
• Manage Google ad settings: adssettings.google.com

Note: Depending on your jurisdiction (e.g., EEA/UK), a consent banner may be required for ad cookies. We aim to serve non-personalized ads by default where applicable.

Service providers & location

Front-end is hosted on Hostinger; API runs on Render. Processing may occur in data centers outside your country. We use TLS (HTTPS) in transit and rely on provider-managed protections at rest.

Retention

• Temporary files: deleted automatically after your merged file is sent.
• Rate-limit entries: in-memory for up to 60 minutes.
• Server logs: minimal metadata retained up to 30 days (or the provider’s default), then purged.

Your rights

Depending on your region (e.g., EEA/UK/California), you may have rights to access, correct, delete, or restrict processing of your personal data. Since we don’t persist your files, requests typically concern logs or IP-based entries. Contact us and we’ll help.

Children’s privacy

DocMerge is not directed to children under 13 (or the age required by your local law). Do not use the service if you are under the applicable age.

Security

We use HTTPS, least-privilege server permissions, and ephemeral temp folders. No internet service is 100% secure; please avoid uploading highly sensitive documents.
